To all where it may concern:

Be it known that l, RALPH W E. HAYES, a citizen of the United States,residing at tiralva, in the county of Henry and State of lfllinois, haveinvented certain new and useful Improvements in Cultivators, of whichthe following is a specification.

This invention relates more particularly to a casting which forms amounting for an arch connecting frame, and which also forms a mountingfor the shovels and rakes.

One object of the invention is to so construct this casting that it isreversible, there by enabling one casting to serve for use on eitherside of the arch connecting frame.

Further objects of the invention are, to provide means for enabling anadjustment of the arch frame transversely or longitudinally of itself;to provide for an adjustment of the foot levers and rake members withrespect to the casting; to so position the foot lever with respect: tothe pivotal center of the casting that an etlicient leverage will beobtained when it is desired to move the shovels to enable them to dodgean obstruction; and to provide a brace between the bar attached to thetongue of the cultivator and the arch member, which brace will be secured to each of these members at a point remote from their juncture,thus increasing the rigidity and strength thereof.

The invention further consists in the features of construction andcombination of parts hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of the assembledcultivator having em bodied therein the improvements of the presentinvention; Fig. 2, a plan view of the arch. frame and the castings inwhich it is mounted, and also showing the shovels and rakes in operativeposition; Fig. 3, a side elevation of the parts shown in 2; Fig. 4, afront elevation of the casting which forms the mounting for the archmember, rakes, and shovels Fig. 5, a sectional detail through one of thecastings showing the slot in which the end of the arch member ismounted; Fig. 6, a sectional detail showing the method of securing thestem upon which the shovels are mounted; Fig. 7, a face view of oneportion of the locking members for holding the Specification of LettersPatent.

shovels in position; and Fig. 8, a face view of the other portion of thelocking member for holding the shovels in position.

The device comprises a framework 9, to which is secured the ordinarytraction wheels 10 and tongue 11. The f'amework and the method ofsecuring the wheels and tongue thereto are of any of the ordinary andwell known types at present in use and do not constitute a part of thisinvention. Carried by the frame 9 is a seat 12, as is usual and wellknown in constructions of this character. Adjustment of the frame workabout the axial center of the wheels 10 is accomplished in the usual andwell known manner, through the medium of lever and segment mechanism 13.

Secured to the tongue 11 are companion bars 141: extending upon oppositesides of the tongue; and, as shown in Fig. 2, one end of one of the barsis connected to a casting 15 and the end of the other bar is connectedto a casting 16. Each of these castings is similar in construction andit is thought that a description of one, together with the variousfunctions performed thereby, will be suflicient for the purpose ofdescribing the present invention. Hence, hereinafter when the termcasting is used, it is understood that reference is not being made to asingle casting. but is being made to each casting of the pair which isemployed with the device. Indeed, I consider one feature of my invention to lie in the peculiar and novel construction of the casting, whichenables it to be interchangeable and adapted for use upon either side ofthe machine; that is to say, which can be used on either the right orleft hand side of the arch member. This is an important point in devicesof this nature, because of the fact that it reduces materially the costof construction, being all. made from the same pattern, and whenever adealer has two castings on hand, he has a complete equipment for amachine. Obviously, if the castings were of different types, it wouldfrequently happen that the dealer might find himself well supplied withthose adapted to be used on one side of the arch, but lacking in thoseadapted to be used on the opposite side. It will thus be seen thatmaterial advantages would arise from the employment of a single form ofcasting for use on either side of the machine.

The bars let are connected to the castings by means of a U-shaped strap17, which surrounds a pin 18 extending through oppositely disposed ears19 formed with the castings; and a pivotal connection between thecasting and the bars let is effected by means of a bolt or othersuitable device 20 which extends through the strap 17 and the bar 14, asbest shown in Fig. 3. This connection serves to enable a verticalpivotal movement between the bar and cast-ing, since the strap is sosecured to the casting as toprevent vertical pivotal movement betweenthese two parts. Adjacent the outer edges of the castings are securedcompanion rods or stems 21, which are provided with horizontallyextending ends 21 adapted to receive a clamping member 21 secured to theshovels 22, the shovels being of any ordinary and well known typeadapted to perform the work allotted to devices of the nature of thepresent invention.

The stems 21 are held between a fixed clamping member 23, formedintegral with the casting, and a movable clamping member 22 formedseparably from the casting, as best shown in Figs. 6 and 8. The movableclamping member comprises a semi-circular collar, which, at one end, isprovided with an ear 24 adapted to receive a bolt 25, and at its otherend with a lug 26, which is adapted to be inserted through a slot 27formed adjacent the edge of the fixed clamping mem her; and the lug 26is of a formation, as best shown in Fig. 6, so that when it is insertedinto the slot it will lie behind the metal forming the end of the fixedclamping member and be interlocked therewith.

The fixed clamping member comprises a semi-cylindrical recess 28 adaptedto cooperate with the recess of the clamping member 23 and form a seatfor the reception of the upper end of the stem 21; and the fixedclamping member terminates, at its in ner end, in an ear 29, registeringwith the ear 2 1, the bolt 25, when the device is as sembled, passingthrough both ears, and thus forming a secondary means for locking thetwo clamping members together and securing the stem 21 in position.

The casting is provided with a slot 30, which, as shown in Figs. 2 and1, extends through the casting at an angle with respect to the bodyportion thereof; hence, when the arch member 30 is setting at rightangles to the direction of movement of the cultivator, the casting willbe lying at an acute angle thereto, whereby the shovels will be placedout of alinement with one another and will lie at an angle with respectto the movements of the cultivator.

As shown in Fig. 5, the slot 30, through which the ends 30 of the arch3O are entered, is of a curved formation, the distance between the upperand lower edges being less at the center than at the ends. This providesa space at either end of the slot between the upper and lower walls andpermits of movement of the end of the arch within the slot for purposesof adjusting the arch with a movement horizontally. This adjustment isperformed by means of companion set screws 31 which find a bearing inthe upper walls of the slot, extend into the slot, and rest against thatportion of the arch lying therein, at points upon opposite sides of thecenter of the slot. As shown in Fig. 5, openings are made at the top andbottom of the walls of the slot to receive these set screws, but thescrews are only entered into the top walls, the holes in the bottomwalls being provided so that when the casting is turned upside down foruse upon the opposite side of the arch, a bearing for the screws will beprovided.

As shown in Fig. 5, by loosening the screw upon the right hand side andlowering the screw upon the left hand side, the outer end of the archwill be forced down thus lifting that portion of the arch lying outsideof the casting upward. If the reverse movement of the screws iseffected, the inner end of the arch, or that portion lying to the innerside of the center of the casting, will be thrown downward and the bodyportion thrown downward therewith, the arch in its movement in eitherdirection rocking about the center of the curve at the center of thewalls of the slot. Hence, by means of this peculiar formation of slotand by providing set screws, movement of the arch into and out of theslot, or vertically of itself, is permitted, this being done byloosening both screws and sliding the end of'the arch in the slot; andalso movement of the end of the arch up and down within the slot, orhori zontally of itself, is permitted by means of loosening one of thescrews and tightening the other. Thus an adjustment of the arch bothways is possible without removal from the casting.

Secured to the casting is a foot lever 32 attached by means of a boltand a bolt 34, the latter lying within a slot 35 formed in an ear 36extending from the upper face of the casting. The slot 35 is provided soas to enable adjustment of the foot piece with respect to the casting,whereby it will extend out therefrom at any angle desired.

The foot piece is for the purpose of moving the shovels to enable themto dodge obstructions, which movement is provided for in all machines ofthe class to which that of the present invention belongs; but it will benoted that the foot piece in the present invention is secured at a pointoutside of the supported center of the casting, lying, as

shown more clearly in Fig. 2, outside and to the rear of such supportedpoint. Hence, when pressure is applied to the foot piece for the purposeof moving the shovels, a greater leverage is obtained, the usual methodemployed in all devices, so far as I am aware, being to secure the footlever within the point of support for the castings, which positionevidently would not give as great a leverage as that of the presentinvention, being nearer the fulcrum point.

Positioned below the foot lever is a bar 87, which is secured to thecasting by means of the bolt 33 and a bolt and slot connection similarto the bolt and slot connection 34 and 85 heretofore described, and tothe bar 37 is secured an implement 38, which, as shown, is in the formof a drag or rake, and is utilized for the purpose of leaving a levelcultivation. The instrument is mounted within a semi-cylindrical seat 38formed 011 the end of the bar 37, and is adjustable within said seat bymeans of a bolt 38 operating within a slot 38; and these means, shown inFig. 3, are provided for adjusting the member 38 so that it may beinclined at any angle desired with respect to the ground line. The archmember is secured to the bars 14 by means of a tie rod 89, as best shownin Fig. 3. it will be seen from this figure that the tie rod is securedto the arch member and to the bar 14 at a point removed from their ends,and thus forms a strong and efficient brace.

As shown in Fig. 2, the castings 15 and 16 are at an angle with respectto the arch member, and the shovels when mounted in position lie atright angles to the casting; hence, the shovels are positioned so thatthe inner ends of each shovel of the pair of shovels lying upon eachside of the arch extend toward the shovels lying upon the opposite sideof the machine, and thus a cut of considerable width is effected, andeach shovel is lying in such relation with respect to the other shovelconstituting the pair as to cause the cuts produced by each of theshovels to overlap one another, so that a cut is produced on each sideof the machine of substantial width.

It will be noted that the foot levers are actuated by a direct downwardthrust from the foot of the operator, and this thrust tends to embed theunderlying pair of shovels more deeply in the ground on the side of thedepressed lever, which forcing of this pair of shovels more deeply inthe ground increases the resistance on such pair of shovels and causesthe arch frame and connections to swing toward the side of the moredeeply depressed shovels, thereby permitting the movement of the shovelsnecessary to enable them to dodge an obstruction. The foot levers ineach case are connected at points outside of the points of suspensionfor the frame, so that when the foot lever on one side of the machine isforced down, the arch frame and connections will swing from their pointsof suspension, and the farther point of suspension will afford afulcrum, which method of applying the power increases the leverage ascompared with a construction in which the foot levers act at pointsintermediate the two points of suspension.
